The max values for (time, iterate n, and iterate n+1) for the data in the newPoints map
Holds the association of the series name to the current max time for that series
The min values for (time, iterate n, and iterate n+1) for the data in the newPoints map
Holds the association of the series name to the current min time for that series
Map holding the name of the series (the time-series identifier) and the associated
data points for that time-series (map(series_name -> array(datum)))
Intended base interface for chart data. All chart data need to hold a Set of series names.
